②White emission using mixtures of CdSe quantum dots and PMMA as a phosphor
This paper explain WLED that have mixture stucture (one single chip(emit blue light) and cdse/PMMA quantum dots). CdSe quantum dots are synthesized by the wet chemical method using CdO and Se powder as precursor. And they control the size of quantum dot and mix the phospors(PMMA).
These quantum dots have three differe

thermal management because these solid-state devices are compact, light weight, have no moving parts, and are capable of providing localized, high-flux, on-chip active cooling.
Table I provides the thermal and electrical properties for three typical thermoelectric materials, Bi2Te3, SiGe, and single-crystal silicon, at room temperature

controlled to the tightest possible. In the tables, this means the double patterning line width must be controlled to the specification that an MPU gate line width would be controlled to. The mask specifications needed to support this specification are shown in the bottom rows. The matched double patterning mask image placement must be tighter than a single mask overlay by the square root of 2. T
acid (vitamin C) is o-quinone and the oxidation reduction reaction, causing ・ himself as the dehydro-ascorbic acid is oxidized to o-quinone to be reduced because catechol. At second test, we can confirm possiblity of time control follow concentration of inhibitor.
What will be done in the next meeting :
◦ we will have meeting for an investigation about experimentation.
→ ALD is based on the sequential use of a gas phase
chemical process. ALD film growth is self-limited and
based on surface reactions, which makes achieving
atomic scale deposition control possible.
